San Diego County is a county located in the southwestern corner of the State of California . It is the south-westernmost county in the 48 contiguous United States . The City of San Diego is its county seat and by far the largest city in the county. According to the census of 2010 , San Diego County had a population of 3,095,313 people, making it the second most populous county in California, following Los Angeles County .

San Diego County has 70 miles (110 km) of coastline. Most of the county has a mild Mediterranean climate to semiarid climate , though there are mountains that receive frost and snow in the wintertime. ^{[ 2 ]}

There are also 16 naval and military installations of the U.S. Navy , U.S. Marine Corps , and the U.S. Coast Guard in San Diego County. These include the Naval Base San Diego , Marine Corps Base Camp Pendleton , Marine Corps Air Station Miramar , and Naval Air Station North Island .

San Diego County defines the metropolitan statistical area of San Diego-Carlsbad-San Marcos and as Greater San Diego . San Diego County is also part of the San Diego–Tijuana metropolitan area . This area has about five million people and it is the largest metropolitan area shared between the United States and Mexico .

Arising from an effort by the state government to identify regional economies, San Diego County and Imperial County are part of the Southern Border Region , one of nine such regions. As a regional economy, the Southern Border Region is the smallest but most economically diverse region in the state. However, the two counties maintain weak relations and have little in common aside from their common border. ^{[ 3 ]}

From north to south, San Diego County extends from the southern borders of Orange County and Riverside County to the Mexico–United States border and Baja California . From west to east, San Diego County stretches from the Pacific Ocean to its boundary with Imperial County.

History

The area which is now San Diego County has been inhabited for more than 10,000 years by Kumeyaay (also called Diegueño), Luiseño , Cupeño and Cahuilla Indians. ^{[ 4 ]}

In 1542, the Portuguese-born explorer Juan Rodríguez Cabrillo , sailing for Spain, claimed San Diego Bay for the Spanish Empire , and he named the site San Miguel . ^{[ 5 ]} In November of 1602, Sebastián Vizcaíno surveyed the harbor and what are now Mission Bay and Point Loma and named the area for Saint Didacus , a Spaniard more commonly known as San Diego . ^{[ 6 ]} European settlement in what is now San Diego County began with the founding of the San Diego Presidio and Mission San Diego de Alcalá by Spanish soldiers and clerics in 1769. ^{[ 7 ]} This county was part of Alta California under the Viceroyalty of New Spain until the Mexican declaration of independence . From 1821 through 1848 this area was part of Mexico .

San Diego County became part of the United States as a result of the Treaty of Guadalupe Hidalgo in 1848, ending the U.S.-Mexican War . This treaty designated the new border as terminating at a point on the Pacific Ocean coast which would result in the border passing one Spanish league south of the southernmost portion of San Diego Bay , thus ensuring that the United States received all of this natural harbor.

San Diego County was one of the original counties of California, and it was created at the time of California statehood in 1850. ^{[ 8 ]}

At the time of its establishment in 1850, San Diego County was relatively large, and included all of southernmost California which was south and east of Los Angeles County . As such it included areas of what are now Inyo County and San Bernardino County , as well as all of what is now Riverside County and Imperial County . ^{[ 8 ]}

During the later part of the 19th century, there were numerous changes in the boundaries of San Diego County, when various areas became separated for the counties mentioned above. The most recent changes were the establishments of Riverside County in 1893 ^{[ 9 ]} and Imperial County in 1907. ^{[ 10 ]} Imperial County was also the last county to be established in California, and after this division, San Diego no longer extended from the Pacific Ocean to the Colorado River , and it no longer covered the entire border between California and Mexico.

Geography

According to the 2000 census, the county has a total area of 4,525.52 square miles (11,721.0 km ² ), of which 4,199.89 square miles (10,877.7 km ² ) (or 92.80%) is land and 325.62 square miles (843.4 km ² ) (or 7.20%) is water. ^{[ 11 ]} The county is larger in area than the combined states of Rhode Island and Delaware. ^{[ 12 ]}

San Diego County has a varied topography. On its western side is 70 miles (110 km) of coastline. ^{[ 13 ]} Most of San Diego between the coast and the Laguna Mountains consists of hills, mesas , and small canyons . Snow-capped (in winter) mountains rise to the northeast, with the Sonoran Desert to the far east. Cleveland National Forest is spread across the central portion of the county, while the Anza-Borrego Desert State Park occupies most of the northeast. Although the western third of the county is primarily urban, the mountains and deserts in the eastern two-thirds of the county consist primarily of undeveloped backcountry . Most of these backcountry areas are home to a native plant community known as chaparral . San Diego County contains more than a million acres (4,000 km²) of chaparral, twice as much as any other California county. ^{[ 14 ]}

North San Diego County is known as North County ; the exact geographic definitions of "North County" vary, but it includes the northern suburbs and sometimes certain northern neighborhoods of the City of San Diego .

The eastern suburbs are collectively known as East County , though most still lie in the western third of the county. The southern suburbs and southern detached portion of the city of San Diego, extending to the Mexican border, are collectively referred to as South Bay .

Periodically the area has been subject to wildfires that force thousands to evacuate. The most recent have been the Cedar Fire in 2003 and the Witch Creek Fire in 2007. California defines a fire season in which fires are most likely to occur, usually between the months of late July and late October (which are the driest months of the area). Signs are posted in numerous spots of the county providing information on the level of threats from fires based on weather conditions. Script error

Climate

Under the Köppen climate classification system, the San Diego area straddles areas of Mediterranean climate (CSa) to the north and semi-arid climate (BSh) to the south and east. ^{[ 15 ]} As a result, its often described as "arid Mediterranean" and "semi-arid steppe". San Diego's climate is characterized by warm, dry summers and mild winters with most of the annual precipitation falling between November and March. The city has mild, mostly dry weather, with an average of 201 days above 70 °F (21 °C) Template:Convert/track/abbr/on and low rainfall (9–13 inches (23–33 cm) annually). Summer temperatures are generally warm, with average highs of 70–78 °F (21–26 °C) and lows of 55–66 °F (13–19 °C). Temperatures exceed 90 °F (32 °C) Template:Convert/track/abbr/on only four days a year. Most rainfall occurs from November to April. Winter temperatures are mild, with average high temperatures of 66–70 °F (19–21 °C) and lows of 50–56 °F (10–13 °C).

The climate in the San Diego area, like much of California, often varies significantly over short geographical distances resulting in microclimates . In San Diego's case this is mainly due to the city's topography (the Bay, and the numerous hills, mountains, and canyons). Frequently, particularly during the "May gray/ June gloom " period, a thick marine layer will keep the air cool and damp within a few miles of the coast, but will yield to bright cloudless sunshine approximately 5–10 miles (8.0–16 km) inland. This happens every year in May and June. ^{[ 16 ]} Even in the absence of June gloom, inland areas tend to experience much more significant temperature variations than coastal areas, where the ocean serves as a moderating influence. Thus, for example, downtown San Diego averages January lows of 50 °F (10 °C) and August highs of 78 °F (26 °C) . The city of El Cajon, just 10 miles (16 km) northeast of downtown San Diego, averages January lows of 42 °F (6 °C) and August highs of 88 °F (31 °C) . ^{[ 17 ] [ 18 ]}

Rainfall along the coast averages about 10 inches (25 cm) of precipitation annually, which occurs mainly during the cooler months of December through April. Though there are few wet days per month during the rainy period, rainfall can be heavy when it does fall. However, the rainfall is greater in the higher elevations of San Diego. Some of the higher areas of San Diego can receive 11–13 inches (28–33 cm) of rain a year.

Media

The major regional paper is The San Diego Union-Tribune , also known as U-T San Diego , which is ranked 25th in the country. ^{[ 31 ]} The Union-Tribune serves both San Diego County and neighboring Imperial County . The former North County Times , based in Escondido and serving portions of Riverside County and North County , was purchased by the Union-Tribune in 2012 and is now the North County interest section of the Union-Tribune. ^{[ 32 ]} The Los Angeles Times is also delivered. Many of the area's cities, towns and neighborhoods have their own local newspapers. Privately published papers like the Military Press Newspaper and the Navy Dispatch serve the military community both on and off base.

Law, government and politics

Government

The Government of San Diego County is defined and authorized under the California Constitution , California law , and the Charter of the County of San Diego. ^{[ 33 ]} Much of the Government of California is in practice the responsibility of county governments such as the Government of San Diego County. The County government provides countywide services such as elections and voter registration, law enforcement, jails, vital records, property records, tax collection, public health, and social services. In addition the County serves as the local government for all unincorporated areas. ^{[ 34 ]} Some chartered cities such as San Diego and Chula Vista provide municipal services such as police, public safety, libraries, parks and recreation, and zoning. Other cities such as Del Mar and Vista arrange to have the County provide some or all of these services on a contract basis.

The county government is composed of the elected five-member Board of Supervisors , several other elected offices and officers including the Sheriff , the District Attorney , Assessor/Recorder/County Clerk , and Treasurer/Tax Collector , and numerous county departments and entities under the supervision of the Chief Administrative Officer such as the Probation Department . In addition, several entities of the government of California have jurisdiction conterminous with San Diego County, such as the San Diego Superior Court .

Under its foundational Charter, the five-member elected San Diego County Board of Supervisors is the county legislature. The board operates in a legislative, executive, and quasi-judicial capacity. As a legislative authority, it can pass ordinances for the unincorporated areas (ordinances that affect the whole county, like posting of restaurant ratings, must be ratified by the individual city). As an executive body, it can tell the county departments what to do, and how to do it. As a quasi-judicial body, the Board is the final venue of appeal in the local planning process.

As of January 2013 the members of the San Diego County Board of Supervisors are:

• Greg Cox, District 1, Chairman


• Dianne Jacob, District 2


• Dave Roberts , District 3


• Ron Roberts, District 4 (no relation)


• Bill Horn, District 5

For several decades, ending in 2013, all five supervisors were Republican , white , graduates of San Diego State University , and had been in office since 1995 or earlier. The Board was criticized for this homogeneity, which was made possible because supervisors draw their own district lines and are not subject to term limits. ^{[ 35 ]} (In 2010 voters put term limits in place, but they only apply going forward, so that each incumbent supervisor can serve an additional two terms before being termed out. ^{[ 36 ]} ) That pattern was broken in 2013 when Slater-Price retired; she was replaced by Democrat Dave Roberts, who won election to the seat in November 2012 and was inaugurated in January 2013. ^{[ 37 ]}

The San Diego County Code is the codified law of San Diego County in the form of ordinances passed by the Board of Supervisors. The Administrative Code establishing the powers and duties of all officers and the procedures and rules of operation of all departments.

The county motto is "The noblest motive is the public good." County government offices are housed in the historic County Administration Building, constructed in 1935-1938 with funding from the Works Progress Administration . ^{[ 38 ]}

San Diego County has historically been thought of as a Republican stronghold. The Republican presidential nominee carried the county in every presidential election from 1948 through 2004, except in 1992 when Bill Clinton won a plurality. In 2008, Barack Obama became the first Democratic presidential candidate to win a majority of votes in San Diego County since World War II; he won a majority of county votes again in 2012.

The city of San Diego itself is more Democratic than the county's average and has voted for Democrats Clinton, Gore, Kerry, and Obama, respectively, in the last six presidential elections. In the 2004 presidential election, San Diego, Encinitas, National City, Del Mar, and some other areas voted for John Kerry ; San Marcos, Escondido, Carlsbad, Oceanside, Coronado, Santee, Poway, El Cajon, and Vista overwhelmingly backed George W. Bush . Chula Vista, La Mesa, Lemon Grove, Solana Beach, and Imperial Beach are considered swing areas of the county – Chula Vista and Imperial Beach narrowly backed Al Gore in 2000 but narrowly voted for Bush in 2004, while Solana Beach switched from Bush in 2000 to Kerry in 2004. La Mesa narrowly voted for Bush both times, and Lemon Grove narrowly went Democratic both times. However, all of these swing areas as well as Oceanside voted for Obama in 2008.

One unique feature of the political scene is the use of Golden Hall, a convention facility next to San Diego's City Hall, as "Election Central." The County Registrar of Voters rents the hall to distribute election results. Supporters and political observers gather to watch the results come in; supporters of the various candidates parade around the hall, carrying signs and chanting; candidates give their victory and concession speeches and host parties for campaign volunteers and donors at the site; and television stations broadcast live from the floor of the convention center. ^{[ 41 ]} The atmosphere at Election Central on the evening of election day has been compared to the voting portion of a political party national convention. ^{[ 42 ]}

Chavez (R); District 77, Brian Maienschein (R); District 78, Toni Atkins (D); District 79, Shirley Weber (D); and District 80, Ben Hueso (D). ^{[ 43 ]}

In the State Senate , all of the 39th district and parts of the 36th, 38th and 40th districts are in the county. As of January 2013 senators are: District 36, Joel Anderson (R); District 38, Mark Wyland (R); District 39, Marty Block (D); and District 40, vacant pending special election in May 2013.

On Nov. 4, 2008 San Diego County voted 53.8% for Proposition 8 which amended the California Constitution to ban same-sex marriages, thus restoring Proposition 22 which was overturned by a ruling from the California Supreme Court . However the city of San Diego, along with Del Mar, Encinitas, and Solana Beach, voted against Proposition 8. ^{[ 44 ]}
